Jean-François BUREL (ID: 000000f08319cf43) Voted 2 ★ - Updated 07/24/2023 Most of the time, on the last version, it asked to update the password while it has not been changed, if I look into the "new password" I can see it is only saving part of the password, which will result in the loss of the saved password and worst, it will be a wrong password saved as it will be partially saved...... also it is very slow sometime to pop up with the password, it is quickier to put in the password myself....

Daniel P (ID: 000000312eb6b7fa) Voted 1 ★ - Updated 07/20/2023 Try the export function before putting too much work into C2 Password. My exports are missing data - crucial data like PASSWORD, URL, etc. Aside this show-stopper, the user interface offers fields such as IP, SSID and other useful fields which are not even considered as header in the export. This means even if the export was working as expected, the data entered here will never be attempted to export. Waste of my time for sure. As with many password solutions the import/export of passwords presents the biggest hurdle for me. My current solution I want to move from is KeePass with 500+ passwords.
